How do I linearize a square root graph?

  1. Sep 23, 2014 #1
    1. The problem statement, all variables and given/known data
    These are the Points.
    X values: 0, 1.98, 3.96, 5.94, 7.92, 9.9
    Y values: 1.98, 7.13, 9.08, 11.04, 12.57, 14.51
    I need to find the original equation and the linear equation. I can't seem to find the line for square root graphs.

    2. The attempt at a solution

    I know it's a square root graph, but that's about it.

    You know or suspect that ##y\propto\sqrt{x}##?
    Then plot ##y^2## vs ##x##.

    Another way of getting a straight line is to plot the data using log scales for both variables.
